# Catalysis & porous materials Source: https://powdchem.com/applications/catalysis-porous-materials/ Page type: Application guide Applications Catalyst and porous-powder sourcing for a specified reaction, adsorption or separation study, with form and pretreatment conditions kept clear. [Narrow your material choices]() [Ask about your requirement]() ## Do you need an active catalyst or a support to load yourself? Separate the active component, support and supplied form before comparing prices. Narrow your material shortlist | Your requirement | Start by comparing | What can change the choice | Explore materials | | --- | --- | --- | --- | | You need a supported catalyst | The named metal/support combination and loading | The active-metal loading is a composition requirement. Powder, wet catalyst and shaped catalyst need distinct handling and process briefs. | [Palladium on carbon powder (Pd / C)]()[Platinum on carbon powder (Pt / C)]()[Platinum on alumina powder (Pt / Al2O3)]() | | You will deposit the active component | The specified carbon, alumina or other support | Surface chemistry and pore structure affect preparation. Compare the same activation and surface-area methods. | [Gamma alumina support powder (Al2O3)]()[Aluminum oxide powder (Al2O3)]() | | You are screening an adsorbent framework | A named MOF or zeolite | Target molecule, moisture and activation history help narrow candidates; total surface area alone is insufficient. | [ZIF-8 powder (Zn(C4H5N2)2)]()[UiO-66 powder (Zr6O4(OH)4(C8H4O4)6)]()[Zeolite powder (Aluminosilicate framework; composition varies)]() | Start with the task closest to yours. The examples identify material requests; a proposed grade still needs to fit your process and evaluation. ## Supported catalyst powders Select the active metal, support and loading. Here loading means the amount of active component on the support. ### Materials to explore [Palladium on carbon powder (Pd / C)]() [Platinum on carbon powder (Pt / C)]() [Platinum on alumina powder (Pt / Al2O3)]() [Catalysts & Supports]() ### What changes the comparison Keep supplied treatment state, loose powder form and the reaction/pretreatment conditions with the evaluation. [Discuss this task]() ## Catalyst supports If you prepare the catalyst yourself, request the support chemistry and pore or surface requirements separately from the active component. ### Materials to explore [Gamma alumina support powder (Al2O3)]() [Zeolite powder (Aluminosilicate framework; composition varies)]() [Aluminum oxide powder (Al2O3)]() [Catalysts & Supports]() [Oxide Powders]() [High-Purity & Specialty Oxides]() ### What changes the comparison Compare pretreatment, surface-area method and particle form before assessing a support change. [Discuss this task]() ## Framework and adsorption studies Choose the framework identity or porous-material system required by the adsorption or separation study. ### Materials to explore [ZIF-8 powder (Zn(C4H5N2)2)]() [UiO-66 powder (Zr6O4(OH)4(C8H4O4)6)]() [HKUST-1 powder (Cu3(C9H3O6)2)]() [Mesoporous silica powder (SiO2)]() [MOF & Porous Materials]() ### What changes the comparison Activation means the preparation used before measurement or use; record it with the target gas or liquid and adsorption conditions. [Discuss this task]() ## Bare precious-metal powders Use the precious-metal directory when you need elemental powder rather than a metal deposited on a support. ### Materials to explore [Platinum powder (Pt)]() [Palladium powder (Pd)]() [Precious Metal Powders]() ### What changes the comparison Compare metal assay basis, particle morphology and supplied condition. [Discuss this task]() ## Prepare a useful comparison A reference datasheet or your existing material code is useful. If you are still exploring, describe what you are making and which result needs to change. - Active phase/support or framework identity - Loading, powder form and pore requirements - Activation/pretreatment and supplied state - Reaction/adsorption conditions and sample plan [Prepare an application inquiry]()
